Design and Construction
Harley Raceboats built the Mustang 30 with a solid fiberglass hull and deck. The beam measures 8 feet 1 inch against a 29-foot-6-inch overall length, giving a length-to-beam ratio of 3.63 — a comparatively narrow footprint that favors sea-kindly behavior over expansive interior volume. The displacement-length ratio of 205 places her toward the heavier end of the modern light-displacement spectrum, while the wetted surface of about 236 square feet and an immersion rate of 658 pounds per inch describe a hull that settles predictably under load. The capsize screening value of 1.82 and a Motion Comfort Ratio of 21.6 both point to a stable, forgiving platform for her size.
Rig and Handling
The Mustang 30 is built with a fractional rig, a configuration that keeps the masthead loads lower and shifts driving power toward the mainsail. Period specifications list jib and genoa sheets at 29.5 feet and 3/8 inch diameter, a mainsheet of 73.8 feet in the same diameter, and spinnaker sheets of 65 feet — dimensions consistent with a compact sloop worked by a short crew. The fin keel with bulb draws between 5.61 and 5.91 feet depending on load, which keeps her out of the shallowest anchorages but still admits most marina entrances bulb keel draws 5.61 to 5.91 feet. The calculated maximum speed of about 4.7 knots sits well below the theoretical displacement-hull speed of 6.5 knots for her length, confirming she is no offshore passage racer but a balanced coastal cruiser.
Accommodations
The 23-foot-3-inch waterline and 8-foot-1-inch beam define a compact volume below, consistent with a cruiser-racer of under 100 units produced.
The Verdict
The Mustang 30 is a modest-production British design from the late 1980s that pairs a solid fiberglass hull with a fractional rig and bulb fin keel. Her stability numbers and comfort ratio suggest a steady, manageable coastal boat rather than a stripped racer, and the limited build count means she is an uncommon sight afloat.
Pros
- Solid fiberglass hull and deck construction
- Stable profile: capsize screening 1.82, Motion Comfort Ratio 21.6
- Fractional rig with manageable sheet dimensions for short-handed sailing
- Bulb fin keel draws within most marina limits
Cons
- Fewer than 100 built, limiting fleet support and spares commonality
- Calculated max speed of 4.7 knots trails her theoretical hull speed
